Problems solved by technology

These hazards can be particularly dangerous to the motorcycle rider if not seen especially when racing.
Thus it is risky for an off-road motorcy

Embodiment Construction

[0059]FIGS. 1-4 illustrate how a visor 50 with an integral mirror 52 of this invention is used when affixed to a motorcycle helmet 54.

[0060]In particular FIGS. 1-2 illustrate how a first motorcycle rider 40 can see a second motorcycle rider 42 to his left and rear by turning his head slightly to the left and tilting his head slightly upwards on his left to see an image of the second motorcycle rider 42 in the mirror 52.

[0061]Similarly, FIGS. 3-4 illustrate how the first motorcycle rider 40 can see another motorcycle rider to his right and rear by turning his head slightly to the right and tilting his head slightly upward on his right to see an image of the other motorcycle rider in the mirror 52. It can be seen that the rider does not have to be twist his torso around at all.

[0062]It can also be seen in FIG. 2 that while viewing the image of the second motorcycle rider 42 in mirror 52, the first motorcycle rider 40 could easily shift his vision from the mirror to straight ahead, i.e...

Abstract

A visor that is especially useful for motorcycle riders and especially for off-road motorcycle racing. The visor has a sun shade member and a mirror. The mirror is affixed to an under surface of the sun shade member. The mirror has a continuous convex surface with a curvature that is free of discontinuations and step changes. The mirror is spaced an effective distance from the user's eyes and has a lateral span and a longitudinal span that are large enough so that the helmet wearer can simultaneously see approximately the same field of view to a side and rear with each eye by a slight turn and tilt of the user's head while an unobstructed line of sight in the direction of travel is retained. The invention also includes a mirror that can be retrofitted to various sun shade members and a kit for retrofitting the mirror in existing sun shade members.

Description

BACKGROUND OF THE INVENTION[0001]Riders of two wheel vehicles such as bicycles and motorcycles have conceived a variety of devices for appraising activity occurring behind their vehicles. For example, U.S. Pat. No. 3,594,069 disclosed a helmet-mountable face shield with single planar mirror positioned below eye level to reflect the user's line of sight rearward and below the maximum width of the helmet. U.S. Pat. No. Des. 224,821 disclosed a helmet-attachable visor with spaced apart left and right rearward directed planar mirrors. U.S. Pat. No. 3,804,495 disclosed a helmet-mounted visor with a prism that directs the wearer's line of sight upwards and an adjustable planar mirror that then directs the line of sight back over the top of the helmet. The mirror is attached to an upright support mounted on the top of the visor.[0002]More complex devices for other uses have also been conceived. For example, U.S. Pat. No. Re 28,847 disclosed a pilot's helmet with an optical system having a ...
